772ef5de19 utils/sdp: improved string handling 
- use snprintf instead of strncat (better behavior - always appends \0 and
no need to subtract 1 from len /and expecting that there is \0 at the end)
- use actual string length with sizeof than STR_LEN (which may get
removed because it is misleading in respect to global STR_LENi value)

6b03287fa0 utils/sdp: use CRLF 
CRLF should be used in SDP (the same as for HTTP for robots.txt+security)

f28371c2e0 utils/sdp: separate and export PT+rtpmap fn 
Separated packet type computation + eventual rtpmap generation to a
separate function, that may be used also by RTSP.

731a48e94f rxtx/sdp: default to mjpeg+mp3 
Those doesn't need to be signalized in any way (PT is defined), so that
the receiver can play the streams directly without SDP - eg. `ffplay
rtp://[::1]:5004` (and similarly on port 5006).

MP3 (just added std TX) is set as default for RTSP as well - perhaps
not a big difference if MP3 or Opus so we do not need to handle two
cases. Also MP3 could be more compatible.

e872453595 rxtx/sdp: print receiver for the stream

specified receiver.

eb0f52e686 fix cycle in win_has_ancestor_process 
In W11, there is a cycle between processes services.exe and wininit.exe:
```
[utils/win] have_ancestor: services.exe PID: 788, PPID: 892
[utils/win] have_ancestor: wininit.exe PID: 892, PPID: 788
```
which caused infinite cycle between these 2 processes.

bb2a72f67f issue a warning in legacy W10 terminals (PS/cmd) 
Those terminal emulators block stdout/stderr output when scrolled,
which effectively stops UltraGrid. The behavior doesn't occur in MS
Terminal app, which is encouraged instead.

Note that Windows Terminal still runs cmd.exe or powershell.exe as a shell
while the cmd/PS process can acts like both terminal emulator and
shell. We also do not trigger the warning if UG is run from within
MSYS2 terminal.

c074bdfd41 vcap/dshow: GetSubtypeName - handle non-printable characters 
added resolve_fourcc to utils/string

   - fixed wrong signal.h include guard (it should be definitely included
   in mac, it was perhaps meant to be MSW, but it is needed there too)
   - removed config*h

45f51f8bb0 display_gl_get_property: assert correct size 
Enough space is rather assumed because in the oppiste case, hard-to-detect
behavior may occur, especially while the problem is not reported.

bbbf0bc7db JPEG reader: handle quant tables more generically 
- do not assume in reader indices 0 for Y a 1 for Cb/Cr
- check the RTP egligibility later
- handle lavc-compressed JPEG (using only table 0) properly, not as a
hack until today

channel count like mono is signalized in-band in Opus)

c66d4f3194 unit_evaluate_dbl: renamed end_ptr var 
Since now we receive endptr as a parameter, it is somehow misleading to
